Have any of you SHTF guys given any thought to a scenario with EMP.
For those that don't know, EMP is Electro Magnetic Pulse - somethign that was discovered originally to occur during a nuclear detonation. However, science has managed to advance the art to the point of not requiring a Nuclear event to create an EMP. Even worse, it can be created (as I heard at a meeting tonight, from an emergency management person) by a device that can fit into something as small as a brief case.
Now, I'll grant you that this would limit it's effective "effect" radius, however, if one showed up in exactly the right place, a larger area of the communications infrastructure would go down.
Living in Seattle during the last Earthquake, I observed how quickly the cell system became overloaded, and this would simply wipe it out - along with all landlines, etc...
Now I'm thinking, that we've been through situations where cables were cut and an entire half of a city has been without phones and regular communications for a day or two, but I would expect something additional to occur in this situation, to cause widespread panic within the area.
So, what are the comments from the rest of you guys out there? Tin foil hat time? Of course my source is reliable, ex-navy (officer), currently an emergency communications co-ordination director for a very large geographic area. I rather doubt he would be buffalo'ing me.
